铜梁一中李川,Unit1Reading,Bamboo,汉语是我们的母语，我们从学英语开始，就是用汉语来解释和记忆英语的。变“用汉语解释和记忆英语”为“用英语解释和记忆英语”。避免了将英语转换为另一种语言汉语所带来的不便和时间耗费。不但提高了效率，而且久而久之，有可能在头脑中建立起两种思维系统，即在在汉语思维之外，还可以逐步建立起独立的英语思维系统。,用英语解释和记忆英语，本身就是在学习和运用英语，对提高英语语感和英语的阅读理解能力和综合运用能力很有好处。是一举多得的好方法。真正做到了用英语品味英语，越品越有味；用英语理解英语，理解更准确。鉴于本环节初次尝试此种设置，可能有些学生对英语解释不能完全理解，为降低难度，英文解释后面可进一步演示中文解释，学生可再通过中文解释回顾早读课中已预习过的单词，进一步加深记忆。,Readtheexplanationandspeakouttheworditexplains.,thejoint(=placewheretwobonesareconnected)betweenthefootandtheleg,orthethinpartofthelegjustabovethefoot,adj.直的，整齐的，诚实的,adj.纤细的，苗条的,n.脚踝,straight,slim,ankle,continuinginonedirectionwithoutbendingorcurving;tidy,orarrangedinorder;honest,(esp.ofpeople)attractivelythin,acontainerforholdingflowersorfordecoration,thefirstpartofaplanttoappearabovethegroundasitdevelopsfromaseed,oranynewgrowthonanalreadyexistingplant,v.冷却；（使）变冷,n.幼苗；嫩芽；新枝,n.花瓶,n.鸟笼,cool,shoot,vase,birdcage,tocausesth.tobecomeslightlycolder,acontainerinwhichbirdsarekeptsothatpeoplecanlookatthem,tosendsth.,usuallyalargeobjectoralargequantityofobjectsorpeople,toaplacefaraway,v.装上船，航运,aclosedmetalcontainer,esp.acylindrical(圆柱形的)one,inwhichsometypesofdrinkandfoodaresold,ship,n.管，导管；烟斗,n.金属罐,pipe,can,atubeinsidewhichliquidorgasflowsfromoneplacetoanother;ashortnarrowtubewithasmallcontaineratoneend,usedforsmokingesp.tobacco,inallcomeupdowithcutdownatthesametimebemadeofputintotakeoutbemadeinto,Match,使进入；把放入,做成,总共,成长，生长,处理，利用,砍倒,同时,由制成,拿出，取出，去掉,TipsforReadingSkills,在阅读每个段落时，要注意综合运用略读与扫读这两种方法。,略读(skimming)只看文章标题和下标题，以及每个部分或者段落第一行。关注文章中反复出现的关键词。略读时，要花足够的时间去读段落的第一句和第二句，直到完全理解其义，因为第一句往往是该段的主题句（topicsentence），而第二句往往是对前句的延伸（extension）或进一步的解释（explanation）。,通过略读把握文章大意,运用扫读(scanning)，迅速浏览从第三句开始的后面部分，搜寻作者对开头两句的支持句(supportingsentences)，并同时注意文章中间是否有转折词(transition)，因为这些词常常会把文章的思路逆转或加入其它重要的信息。当读到段落的最后一句时，我们又要使用略读，这时必须再次放慢速度(slowdownyourpace)直到完全消化作者对段落的小结(conclusion)，因为该小结有可能与主题句截然相反或引导读者进入下一个段落。,通过扫读寻找特定信息或特定词组,Skimmingtogetgeneralideas,Skimming,1.Bambooisakindof_.A.treeB.grass2.Whichisfittodescribethispassage?Itisa_.A.narration(记叙文)B.exposition(说明文)C.prose(散文)D.poem,Readthepassagequicklyandchoosethebestanswer.,3.Fromthepassage,wecanseethepurposeofthewriteris_.A.toattractcustomersasanadvertisementB.toexplainsomethingaboutbambootopeopleC.totellpeopleastoryaboutbambooD.Alltheabovearenotright,Carefulreadingtosolvedifficultpoints,v.冷却；（使）变冷,cool,Therainhascooledtheair.这雨使天气变得凉快了。,处理，利用,dowith,Whatarewegoingtodowiththeproblem?我们将怎样来处理这个问题呢?,dowith和dealwith的区别：dealwith作“对付，处理”之意时，意同dowith，只不过其中do为vt.，而deal为vi.，故用于特殊问句时，dowith与what连用，而dealwith则与how搭配使用，如：Howdoyoudealwiththisproblem?=Whatdoyoudowiththisproblem?这个问题你怎样处理？,不过dealwith还可意为“与交易，论述、涉及”，如：Ivedealtwiththisstore/personfor20years.我与这家商店/这个人已经做了20年的生意了。Thebookdealswiththisproblem.这本书论述了这个问题。,做成,由制成,bemadeinto,bemadeof,bemade后面可以接不同的介词。其含义也不尽相同，同学们一定要多加注意，切勿混淆。,1.bemadeof.该短语表示“某物由制造而成”（从制成品中可以看出原材料）。如：Thebookshelfismadeofwood.这个书架是由木头制成的。,2.bemadefrom.该短语也表示“某物由制造而成”（从制成品中一般看不出或难以分辨出原材料）。如：Paperismadefromwoodandbamboo.纸是由木头和竹子制造而成的。3.bemadein.该短语表示“某物由某地制造”。如：ThecomputerismadeinJapan.这台电脑是由日本生产的。,4.bemadeby.该短语表示“某物由某个人或集体制造而成”，其中介词by用来强调动作的执行者。如：TheTVsetismadebytheworkersinthefactory.这台电视机是由这个厂的工人制造的。5.bemadeinto.该短语表示“某种原料制成某物”，与bemadeof.和bemadefrom.的意思正好相反。试比较：,Glasscanbemadeintobottles.玻璃可以制成瓶子。Bottlesaremadeofglass.瓶子是由玻璃制成的。6.bemadeupof.该短语表示“某物由组成或构成”。如：Animalbodiesaremadeupofcells(细胞).动物的身体是由细胞构成的。Theclassismadeupoffifty-sixstudents.这个班里有56名学生。,ship,v.装上船，航运,Thegoodswereshippedtotheislandlastweek.货物于上周用船运往该岛。Thecompanyshipsitsgoodsallovertheworld.公司把货物运往世界各地。,Scanningtogetdetailinformation,Scanning,1)Althoughbamboolookslikeatree,itsakindofgrass.2)Allbamboosdontgrowtall.3)Thereare500differentkindsofbambooinall.,4)Allbambooswilldiesoonaftertheybloom.5)Bambooissostrongthatpeopleoftenuseitasgoodmaterialformakingfinepaper.6)Inwarmplacesbamboomaygrowthickerthanamanswaist.7)BamboocanbefoundonlyinChineseandJapanesedishes.8)Bambooisnotonlyusedforbuilding.,Fillinthemissinginformationaccordingtothearticle.,WHAT:Bambooisnot_but_.VARIETY:Thereare_differentkindsofbamboo.Bamboogrowsbestin_and_places.Some_,some_,some_,andsomenever_.,atree,akindofgrass,over500,warm,rainy,growveryfast,bloomandhaveseedseveryyear,bloomonlyonceandthendie,bloomatall,USES:Bambooisusedtobuild_anditcanbeusedaspipesto_.Bambooisalsomadeinto_,_and_.Peopleeveneat_.,housesandbridges,carrywater,paper,goodwalkingsticks,fishingpoles,thetenderyoungshootsofbamboo,Thearticlecanbedividedintothreeparts.Haveadiscussionwithyourpartnerandmarkoutthethreeparts.Thenwritedownthemainideaofeachpart.,PartI(Para._to_)_PartII(Para._to_)_PartIII(Para._to_)_,1,2,Bambooisakindofgrassinsteadofatree.,3,4,Featuresandhabitsofbamboo.,5,11,Variouskindsofusesforbamboo.,Workingroupstocompletethefollowingtasks.,1)Readthearticlecarefullyandtrytofindalltheadjectivesusedtodescribebamboo.2)Imagineanyotheruse(s)bamboomayhaveinthefuture.,high;tall;straight;thin;long;slim,Readthefollowingpoemandunderstandwhataspecteachlineofpoemtriestodescribeaboutbamboo.,根为鞭兮枝为扫，叶为笠兮杆为宝；_报得三春无人晓，仅学有节都长高；_,whatbamboois
